@Billings Public Library Join us as we celebrate the 30th Anniversary of Dolly Parton’s Imagination Library. Sing your heart out to Dolly’s biggest hits with Dollyoke, make a fun craft and participate in our kids-only Dolly Parton Costume Contest. Prizes, photo-ops and cake will round out the party! In addition, if you have not already, you can sign up for Dolly Parton’s Imagination Library-which is a book-gifting program that mails high quality books to children.
